SPECIFICATION forming part of Letters Patent N 0. 695,187, dated March 11, 19021. Application filed September 12, 1901. Serial No. 75,218. (No model.)

To all whom it may concern:

Be it known that 1, CHARLES E. WHITNE Y, a citizen of the United States, residing at Chicopee Falls, in the county of Ham pden and State of Massachusetts, have invented new and useful Improvements in Punching-Bag Apparatus, of which the following is a specification.

This invention relates to punching-bag apparatus, and has special reference to a frame construction for supporting the bag and the impact-ring or abutment against which it is swung to rebound it, the object of the invention being to provide a frame of this description which can be readily secured to the top and one side of the frame of the doorin a manner sufficiently rigid to withstand the shock of the bag against the impact-ring without becomingloosened,afurtherobjectbeingtheproduction of a frame of this description which may be attached to either the right or left hand side of the door-frame and which shall be vertically adjustable to adapt it to doorframes or to persons of varying height, and still another is the production of a frame for supporting an annular abutment for the bag in such manner that the latter may strike the impact-rin g on its outer edge without coming in contact with the frame.

In the drawings forming part of this specification, Figure l is a perspective view of a punching-bag frame embodying my inven tion attached to the right-hand side of a doorframe. Fig. 2 is a view showing the frame attached to the left-hand side of the doorframe and showing the bag-abutment deflecting-ring in section. Fig. 3 is a perspective view similar to Fig. 1 and showing the bagsupporting arm in the lower position.

Referring to the drawings, the frame consists of an arm 1 for supporting the bag and its abutment,which arm is secured at one point to the main frame-bar 2 and at another point to the brace-bar 3, a horizontalbrace-rod 4 extending from the main frame-bar 2 to a point near the outer end of the arm 1. Suitable hooked clamp-rods secure the ends of the bar 3 to the door-frame, all as more fully described in the following specification.

The arm 1 is preferably made of cast-iron in one piece of the bracket form shown, the rear end of which is adapted. to be bolted to the-bars 2 and 3 by means of the clamp-rods A 5 and the thumb-nuts 6 thereon. The forward end of the arm is forked, as shown, the forks being in the plane of the arm and indicated by 7 and spread sufficiently to receive axis of the ring without coming in contact withtheframe parts. Belowtheringorabuir ment 8 the forked ends of the arm 1 converge somewhat and are provided with suitable fiattened portions to which is secured the annular deflectingring 11, which is axially located relative to the ring 8 and is provided with a central aperture 12 for the reception of the end of a cord to which the bag is attached, the under side of the ring being turned out in bell-mouth fashion, as shown. The object of this ring 11 and the peculiar form of its under surface is to provide an obstruction for the cord on which the bag is suspended,whereby said cord during the swinging movements of the bag may come in contact with said curved underisurface of the ring,and thus progressively shorten the radius on which said bag swings and give the bag a quick upward and inward curve toward and against the ring 8. This feature, h0wever,forms the subject of a pending application for Letters Patent of the United States filed by me on February 15, 1901, under Serial No. 47,503.

The frame-bar 2 is a steel bar having suitable dimensions and adapted to extend diagonally across a door-frame, from the top to one side thereof. Each end of this bar is covered with some material, as leather, to provide against marring the wood of the door frame, and preferably the end of the bar bearing against the top of the door-frame is bent up to a degree which will bring it in substantial parallelism with the sides. The object of this is to provide room for several holes 13 through said vertical end to receive the clamp-rod, whereby the arm 1 may be vertically adjusted to a slight degree, whether said arm be in the position shown in Fig. 1 or that shown in Fig. 3. This adjustment would be effected by loosening the clamp-rods on the side of the door-frame and by withdrawing the top clamp-rod and inserting the latter in some other one of the holes 13 and then tightening up said clamp-rods.

To brace the bar 2 and to provide a suitable support for the arm 1, a brace-bar 3 is provided, which when the frame is in either of the positions shown in Figs. 1 and 2 extends from the side of the frame, to which it is clamped by one of the rods 5, as shown, to a point on said bar 2, to which it is secured by a bolt 14, which passes through an L-shaped clip 15 on said bar, a suitable nut securing both the bar 3 and the clip 15 to the bar 2. On that part of the clip projecting outwardly from the bar 2 there is secured by a bolt or screw another brace 4, extending to a point 16 well forward on the arm 1, whereby the latter is rigidly braced against lateral movements. The point of attachment of this brace 4 to the arm is about as much higher than the point of its attachment to the clip 15 as the distance between the side clamp-rods. The purpose of this is to permit the fitting of the brace to the arm when it is in the lower position (shown in Fig. 3) by reversing the bar, so that it will trend downward.

To effect a material change in the height of the arm 1, and consequently of the bag, (indicated by 17,) the brace 3 is removed by looseningthe clamp-rods and bolt 14, which secure it, and placing the end secured by said bolt over the hole 18 on the bar 2, located about midway between its ends, the same bolt being used to hold it inboth places, the lower end of the bar being secured to the side of the door-frame, as seen in Fig. 3, at a point below the lower end of the bar 2 equal to the distance between the position of the two side clamp rods shown in Figs. 1 and 2. The brace-bar 4 is also removed and reversed, so that it may dip downward, and is secured at the same points on the clip 15 and on the arm 1 as in said Figs. 1 and 2.

By means of the herein-described construction an apparatus is provided which can be readily put up in the house and which will be rigid and economical of construction andone whereby the minimum amount of space will be occupied and which is capable of such vertical adjustmentsas will adapt it to be placed on door-frames of varying heights, and the apparatus is so constructed that it may be secured to either side of the door-frame.

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is-

1. A punching-bag apparatus comprising an arm on which the bag is supported, asupporting-frame for said arm, consisting of separable members, and means whereby, by the shifting of said members, the frame may be secured to either side of the doorway.

2. A punching-bag apparatus comprising structure the bag will be located on the same side of the latter.

4. A punching-bag apparatus comprising an arm on which the bag is supported, a supporting-frame for said arm comprising a diagonally disposed bar for extending from one side to the top of a door-frame, and a bracebar having one end secured to said diagonally-disposed bar, and its opposite end adapted to be secured to the side of a door-frame above or below the end of said first-named bar, whereby the position of said arm may be varied vertically, substantially as described.

5. A punching-bag apparatus for attachment to a door-frame, consisting of a bagsupporting arm,-a bar extending diagonally across said frame and secured thereto, a bracebar extending from the first-named bar to the frame, said two bars constituting a support for said arm, and means for securing said brace-bar in different positions relative to.

said first-named bar to adjust said bar vertically, substantially as described.

6. A punching-bag apparatus for attachment to a door-frame consisting of a bag-supporting arm, a diagonally-disposed bar extending from one side to the top of said frame, a brace-bar extending from the frame to said diagonal bar between the ends of the latter, said bars constituting a support for said arm; clamp-rods for securing the bars to the doorframe, and means for securing the bag-supporting arm to said bars, substantially as described.

7. A punching-bag apparatus for attachment to a door-frame consisting of a bag-supporting'arm,abar extending diagonallyacross a corner of said frame, a brace-bar between said first-named bar and the door-frame, said said arm removably attachable to a doorframe or similar structure, substantially as described.

9. A punching-bag apparatus, an impactring or abutment for the bag having an outwardly-facing impact-surface, a deflectingring below and in axial elinelneut with said impact-ring, an L-shaped support for said ring whereby the outwardly-facing surfaces of the letter will not be obstructed.
